Overview
UGREEN EC701 / 35023 provides up to 45W from USB-C and 18W from USB-A, with a 63W combined maximum. USB-C supports fixed PD profiles and PPS from 3.3–11V up to 4.05A for compatible devices. USB-A supports QC 3.0 profiles up to 18W. Unlike many small shared chargers, the exact official specification explicitly states 45W + 18W in dual-port operation.
Best-fit summary: Drivers who want a 45W PPS/PD path for a compatible phone, tablet or lightweight laptop while keeping a separate 18W USB-A output active.
Key features
45W USB-C
Suitable for compatible Galaxy Super Fast Charging 2.0 devices and many tablets or lower-power laptops, subject to cable and device support.
18W USB-A
A dedicated QC 3.0 output for an additional phone or accessory.
63W together
Official exact-SKU data supports 45W + 18W simultaneously rather than a reduced shared split.

USB-C
5V/3A, 9V/3A or 12V/3A; PPS 3.3–11V/4.05A; up to 45W.
USB-A
5V/3A, 9V/2A or 12V/1.5A; up to 18W with QC 3.0-compatible hardware.
Port labels matter: Use USB-C for the priority 45W PD/PPS device and USB-A for the secondary QC-class device.
Exact power allocation
| USB-C alone | Up to 45W. |
|---|---|
| USB-A alone | Up to 18W. |
| USB-C + USB-A | 45W + 18W = 63W total. |
Read the table before buying: 45W is not sufficient for every laptop, and an illustrated 45W phone result requires compatible PPS support plus an adequate cable.
Charging protocols and speed logic
USB-C supports PD 3.0 and PPS, including the 3.3–11V/4.05A range used by compatible 45W-class devices. USB-A supports QC 3.0 up to 18W. Live artwork also lists AFC, FCP, Apple 2.4A and BC1.2 fallbacks. Actual brand charging labels remain device-, cable- and temperature-dependent.
PPS 45W
Compatible Galaxy devices can request a programmable profile, but not every Galaxy model accepts 45W.
PD for Apple/tablets
iPhone and iPad models select their own supported PD rate, often below the hardware ceiling.
QC 3.0 USB-A
The second port can deliver up to 18W to compatible devices while USB-C remains at 45W.
Compatible devices and systems
Phones and tablets
Compatible iPhone, iPad, Galaxy, Pixel and other USB-charged phones or tablets can use the charger with the correct cable. The device still decides the accepted voltage, current and charging label.
Portable electronics
Suitable for USB-charged headphones, cameras, navigation units, handheld consoles, speakers, e-readers and power banks when their input matches a listed profile.
Vehicles
Designed for compatible 12V and 24V accessory or cigarette-lighter sockets. Socket depth, contact condition, fuse rating and whether the outlet stays live while parked are vehicle-specific.
Computers
A USB-C laptop is compatible only if it accepts USB Power Delivery within the stated port ceiling. Some high-performance laptops may charge slowly or only while sleeping.
Compatibility rule: Check whether the exact device accepts 45W PPS/PD. Some laptops need 60W or more, and some phones cap well below 45W.
Use scenarios
Galaxy plus passenger phone
Use the 45W PPS USB-C output for a compatible Galaxy device and USB-A for a second phone.
Tablet plus accessory
Charge a PD tablet from USB-C while headphones, a camera or a power bank uses USB-A.
Lightweight laptop commute
Support a compatible 45W-or-lower USB-C laptop while keeping a small secondary device on USB-A.
Mixed ecosystem travel
Serve a modern USB-C device and a legacy USB-A cable simultaneously at their documented ceilings.
Setup and usability guidance
- Park safely before fitting or changing any cables. Confirm that the vehicle outlet is a clean, dry, undamaged 12–24V DC accessory socket.
- Insert the charger fully. If there is no power, check whether the vehicle energises that socket only in accessory or ignition mode.
- Connect the highest-demand device to the port identified in the power table; then add lower-demand devices one at a time.
- Route every cable away from the steering wheel, pedals, gear selector, handbrake, seat rails and airbag deployment areas.
- When finished, disconnect devices first. Remove the charger if the vehicle keeps the outlet live while parked and prolonged standby draw is a concern.
No software required: The charger is plug-and-play; correct socket fit, port choice and cable routing are the important setup decisions.
Everyday usability and care
Automatic negotiation
There is no manual voltage switch. The charger, cable and device negotiate a mutually supported profile.
Shared-power awareness
Adding a second or third device can change the available power and briefly reset the active outputs.
Cable choice
Use the correct connector and a cable rated for the requested current. A phone cable is not automatically suitable for laptop-class power.
Heat and ventilation
Keep the housing exposed to cabin air. Warmth can be normal; abnormal heat, smell or cycling is not.
The spring contacts are designed for stable insertion, but no charger can compensate for a damaged or unusually shallow socket. Keep the vent ring clear and remove dust only while disconnected.
What this product does
- Converts power from a compatible vehicle accessory socket into regulated USB charging outputs.
- Negotiates a mutually supported charging profile with each device and reallocates available power as connections change.
- Charges phones, tablets, accessories and—only where the stated port power is sufficient—compatible USB-C computers.
- Works without an app, driver, Bluetooth connection or vehicle infotainment pairing.
What this product does not do
- It is not an AC inverter and cannot power equipment that requires a household wall outlet.
- Its USB connectors are power outputs, not data, CarPlay, Android Auto, display or file-transfer ports.
- It cannot force a device to accept more power than the device, cable and protocol permit.
- It does not contain a battery and cannot continue charging after the vehicle socket loses power.
- It does not provide 63W from USB-C; 63W is the sum of 45W USB-C and 18W USB-A.
- Do not rely on it for a laptop whose original adapter is 60W, 65W, 100W or higher without confirming that the computer accepts 45W charging.
What to do
- Use sound, correctly rated cables and place the highest-demand device on the strongest documented output.
- Keep the charger exposed to cabin air and keep the accessory socket free of dust, liquid and conductive debris.
- Expect a brief charging pause when a device is connected or removed; many multi-port chargers must renegotiate power.
- Check the connected device’s input requirement instead of judging compatibility from connector shape alone.
- Disconnect power before cleaning and use only a dry, soft cloth.
- For a compatible 45W PPS session, use a USB-C cable that supports the necessary current and device protocol.
What not to do
- Do not use a wet, loose, scorched, cracked or mechanically damaged vehicle socket, charger or cable.
- Do not cover the charger with fabric or wedge it where ventilation is blocked.
- Do not exceed the stated 12–24V DC input range or connect it to an unverified power source.
- Do not handle connections while driving when doing so could distract the driver or interfere with controls.
- Do not disassemble the housing or continue use after deformation, burning odour, repeated shutdown or abnormal heat.
- Do not generalise laboratory charging times or example-device wattages to every phone.
Warnings and limitations
- The vehicle outlet and its fuse must be capable of supplying the requested load. A weak or damaged socket can cause intermittent charging.
- Charging power normally falls as a battery approaches full charge or becomes warm. This tapering is expected and is not proof of a charger fault.
- Metal and high-output charger bodies can feel warm during normal operation. Stop use if heat becomes excessive or is accompanied by smell, deformation or repeated cut-outs.
- The product is not described as waterproof. Protect it from spills, condensation and wet cleaning.
- A printed wattage is a ceiling under defined conditions, not a promise that every device will draw that amount.
- Some exact live artwork illustrates 30W/20W device draws despite the 45W/18W hardware specification. Those examples reflect connected-device limits, not a revised port table.
Stop-use trigger: Disconnect immediately if you notice arcing, smoke, a burning smell, melted plastic, visible deformation or repeated unexplained power loss.
Troubleshooting
No power
Check ignition/accessory mode, reseat the charger, inspect the socket and test a second known-good vehicle outlet if available.
Charging is slow
Test one device alone, use the strongest documented port, verify the cable rating and check the device battery temperature and state of charge.
Power cuts in and out
Inspect for a loose socket fit, debris, worn side contacts or a damaged cable. Repeated cycling is not normal when connections are unchanged.
Fast-charge label is missing
Confirm that the port, cable and device share the required PD, PPS, QC or manufacturer-specific profile. A standard fallback charge may still work.
Useful diagnostic: If a supported Galaxy device does not show its expected fast-charge label, test USB-C alone, verify PPS support for that exact model and use a known high-current cable.

Product-specific FAQ
What is the maximum output?
Up to 63W total: 45W from USB-C plus 18W from USB-A, including dual-port operation.
How does power change when more than one device is connected?
The official exact-SKU allocation remains 45W on USB-C plus 18W on USB-A when both ports are active.
Can it charge a laptop?
Yes, for compatible USB-C laptops accepting 45W or less. It may charge a higher-demand computer slowly or fail to keep up under load.
Which port should I use first?
Use USB-C for the priority PD/PPS device and USB-A for the secondary QC-class device.
Does it support fast charging?
Yes. USB-C supports PD/PPS up to 45W, while USB-A supports QC 3.0 up to 18W.
Will it work in a 24V truck or commercial vehicle?
It is designed for compatible 12–24V vehicle accessory sockets.
Why can charging briefly stop when another device is connected?
The charger may reset and renegotiate its output when the active port combination changes. A short pause is normal; repeated cycling without a connection change is not and should prompt a cable, socket and device check.
Why is the real charging speed lower than the printed wattage?
The printed figure is a maximum. Device input limits, cable capability, battery level, temperature, active-port sharing and the available power source all influence the real rate.
Does it transfer data or connect to an infotainment system?
No. The USB connections on this charger are for charging power only; they do not carry files, video, CarPlay or Android Auto data.
What is included in the package?
One UGREEN 35023 charger and one user manual are listed. Charging cables are not included.
